HAND -STAPLlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 245,088, dated August 2, 1881.

Application led June G, 1881. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL E. MOWER, of Milford, county of New Haven, State of Connecticut, .have invented an Improvement in Hand-Nailers, of which the following description, in connection with' the accompanying My invention relates to a nailing mac-lip or apparatus for driving staples, it being peciallyintended for use in connection witl'L through and out of'a suitably-formed driving passage in the nose. andhas a magazine'p roadwayfor the staples entering the said pasi-l sage.

way by the driver-bar in descending, the sait driver-bar itself lying across the end of and tion to the passage of the staples,then bearing against the said driver-bar from the roadway into the driving-passage. As the driver-bar ascends the separator *falls in between the staple next the driver-bar and the rest of the column before the driver-bar has passed by and opened the roadway, and thus retains the said column of staples in the roadway after the driver-bar in its further upward movement the next descent ofthe driver-bar, the holding device yielding under the positive action thereof. The staples employed are of uniform thickness from their head or top portion down toward their points, so that when placed in the y roadway they will bear against one another at front and back throughout their length, thus enabling the legs ofthe series of staples to be retained parallel' to one another, thus insuring that Ythe end staple of the driveway-column from the roadway enters in proper position,

C l this being a matter of great difficulty when the staples are constructed in the usual manner,

A separator operated by the diiver-InrgA is removed from the line of staples in the road-"gv l i or' with their pointed legs tapered or inclined in the roadway, their tops are in contact, while spaces are left between their points, so that the staples are free to rock or tip back and forth, and are liable to enter the driveway from" the roadway at an angle, or to have only the head portion lie in the path of the driver-bar,

while the points are tipped back in the roadway, thereby causing the driver-bar, when it strikes the staples, to carry the head of the staple forward, while its points are caught by the roadway, thus inverting the staple or breakng it to pieces.

` Figure'isa sectional View of a nailing apparatus constructed in accordance with my invention Fig. 2, a cross-section of the magazine or roadway; 'Fig 3, details showing two forms of separator that may be employed; Fig. 4, a side elevation, showing slightly different forms of staples employed, and Fig. 5 a perspective view, showing a column of staples as they will lie in the roadway.

The handle a, of suitable and usual form, has a passage, 2, bored therein for the drivingrod b and its retracting-spring c, the said driving-rod being provided with a head, d, and operating in the usual manner. The handle a has screwed into its lower end the nose portion e, provided with the driver-passage 3, of suitable shape, to guide the staples f, one of which is shown in position in the upper part of the said passage, to be operated upon and driven by the driver-bar proper, g, fixed upon the lower end of the drivin g-rod b, the staple being maintained in this position by the .holding device h, shown as a spring-finger lying under the top or bridge portion, 4, ofthe staple. (See Fig. 4,)

The magazine or roadway i, having a channel, 5, (see Fig. 2,) of proper shape to receive the staples, extends outward from the nose portion e of the driver, it being inclined downward toward the driving-passage 3, in which it terminates, to cause the column of staples f therein to tend to fall by their own weight toward and into the said driving-passage, the said column being held, when the driver-bar g and its actuating-rod b are in their normal or elevated position, as shown in Fig. 1, by the holding-point 6 of the separator 7c, mounted loosely on a pivot, 7, in the nose portion c of the driver, and normally held across the upper portion of the passage 5 of the roadway by the action of the spring l.

A cam-lever, fm, pivoted at S in the nose portion e of the driver, has a foot, on', to engage the end of the separator 7c when the projection a of the said cam-lever is struck by the wedge or incline o upon the driving-rod b in the descent thereof, this movement raising the point Gfrom the path ofthe column of staples and permitting them to slide downward until stopped by the driver-bar g, which then extends through the driver-passage 3, across the end of the passage 5 of the roadway. In the succeeding upward movement of the driving-rod the wedge o passes by the projection n of the lever 'In before the driverbar g has passed beyond the passage 5 and Vstaples: therein, and the separator 7c is operated by the springlto insert its point 6 between the staple next to the driverbar g and the rest of the column, thus separating the said staple from the others and leaving it free to drop into the driver-passage 3 as soon as the driver-bar g, in completing its upward movement, has passed by the end of the passage 5, the said staple bein gthen caught and held by the holder h un til the next descent of the driver-bar g.

The separator 7c is slotted where mounted on the pivot 7, to thus admit ot' a longitudinal as well as rocking movement on the said pivot, and in entering between the first and second staples of the column it preferably is forced back a little 011 the pivot, so that as soon as the driver-bar has passed it throws the end staple into the drivin g-passage by the action of the spring l.

The legs of the staples are made of uniform thickness from top to bottom, as shown in Fig. 5, measured in the direction of the column in the roadway, so that each staple is held in fixed position between its neighbors, the legs ofthe staples being made tapering from top to bottom in the direction across the roadway, as shown in Fig. 4, for the purpose of giving them a sharp point or cutting-edge to enter the material to be fastened by them.

This construction of the staples causes them to enter the driver-passage 3 in proper position to be driven, and to pass through the said passage in a true upright position, and by making the bevel on the outside of the legs or projections, as shown in Fig. 4, the points will ineline toward one another as they pass through the material, and upon being clinched will approach one another, thus forming a more or less perfect loop around the material between the said legs.

If the staples be made of round wire the end 6 of the supporterc may be a sharp wedge, the said separators being properly located to bring the points between the first and second staples of the column lying in the roadway and resting against the driver-bar y; but if the staples be made of square wire, as shown in Fig. 5, suitable indentations may be made in the sides of the bridge portion 4, as shown at 9, to receive the tapering points l0 (see Fig. 3) of the end of the separator, which will thus be enabled to enter between the first and second staples and hold the column separated from the said rst staple.

I claiml. The driver-bar and its actuating-rod provided with a wedge or incline, combined with the roadway or magazine and separator, and its actuating cam-lever provided with a projection to be engaged and operated by the said wedge in the descent of the driver-bar, substantially as described.

2. The separator mounted on a pivot and slotted, as described, to admit of both rocking and longitudinal movement on the said pivot, substantially as and for the purpose set forth.

3. That improvement in the method of insuring the uniform feeding in a roadway of a column of chisel-pointed staple-fastenin gs to be driven straight into the material by the driver, which consists in making the top and legs of the staple of uniform thickness measured in the direction ofthe column` in the roadway, whereby the top and legs of each staple at front and rearis kept pressed closely against the parallel sides of the staple next to it in the column as the staples travel down the roadway, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
